A Comparison of Different Kinds of Used Lab Vacuum Pumps

Must read

Vacuum pumps for the laboratory are an essential tool. They have a wide range of uses, from evaporating solvents to filtering to preparing samples. There are a plethora of laboratory vacuum pump models available, making it difficult to settle on a single option. Here, we’ll look at some of the key differences and similarities between popular used lab vacuum pump brands including Welch, Edwards, and Leybold.

Welch Lab Vacuum Pumps

When it comes to laboratory equipment, Welch is a name that is trusted and recognized worldwide. Their selection of laboratory vacuum pumps includes both diaphragm and rotary vane designs. The oil-free nature of Welch’s diaphragm pumps makes them perfect for situations where contamination is a problem. The rotary vane pumps they use are renowned for their quick pumping speed and maximum vacuum pressure.

Edwards Lab Vacuum Pumps

A second well-known manufacturer of laboratory vacuum pumps is Edwards. They supply several different kinds of pumps, such as dry pumps, turbomolecular pumps, and oil-sealed rotary vane pumps. Edwards’ dry pumps provide a clean, oil-free vacuum, while their oil-sealed rotary vane pumps are noted for their reliability and longevity.

Leybold Lab Vacuum Pumps

Leybold is an industry-standard in vacuum pumping, filtration, and system components. They make several different types of laboratory vacuum pumps, such as root and diffusion pumps and dry compressing screw vacuum pumps. When fast pumping rates aren’t as crucial as a low ultimate pressure, Leybold’s dry compressing screw vacuum pumps are the way to go. Their diffusion pumps are employed in high vacuum applications, and their roots pumps are well-known for their fast pumping rates and large gas throughout.

What to Look for in a Laboratory Vacuum Pump

It’s important to choose the proper lab vacuum pump for your needs by thinking through a few considerations before making a purchase. While shopping for a used lab vacuum pump, it’s important to bear in mind the following qualities and factors:

Type of Pump: Rotary vane, Diaphragm, Scroll, and Turbomolecular vacuum pumps are all commercially available options. Certain applications may be better suited to specific pump designs than others, and each design has unique advantages. Thus, the pump type must match your application needs.

Vacuum Level: The necessary vacuum level for your application is another crucial issue to take into account. Many pumps are capable of producing varying degrees of vacuum; hence, it is crucial to determine your precise vacuum level needs before making a purchase.

Flow Rate: Another important factor to take into account is a vacuum pump’s flow rate, which affects how quickly air or other gases may be extracted from the system. Again, the precise application and the quantity of gas that has to be evacuated will determine the necessary flow rate.

Chemical Compatibility: Certain vacuum pumps are made to work with a certain set of solvents or chemicals, while others might not be appropriate for the job.  A pump’s chemical compatibility with the substances you intend to use it on should be carefully considered before making a purchase.

Maintenance Requirements: Vacuum pumps, like any machinery, need periodic upkeep to function at peak efficiency and last as long as possible. While deciding on a vacuum pump, it is crucial to factor in the continuing maintenance requirements and associated expenses.

Cost: In making a major purchase, including that of machinery, it is only natural to think about how much everything will set you back financially. The price of a laboratory vacuum pump varies widely based on the model, its accessories, and its capacity. While deciding on the ideal pump for your needs, it is crucial to take into account your budget and weigh the price against the other considerations we’ve discussed.
